Clear Span Roof Systems
Aluminum's lightweight characteristics allow for larger clear-span capability than structures utilizing steel, concrete and other materials. Creative design and lightweight components provide for installation in 1/3 of the time it takes to install other cover systems. Less time, labor and equipment requirements combine for a low total cost of installation.
Aluminum's excellent strength-to-weight ratios and creative component design yield covers and structures that cannot be achieved with other materials. Clear Span Roof Systems are used for curved roofs and can be custom designed to develop a broad range of shapes and sizes. The single layer aluminum framework is offered as |
either an integral glazing system or integral roof and insulation system. Typical building footprint applications include ellipsoidal, oval, rectangular and circular.
The high strength of a clear span structural system is derived from:
• GEOMETRIC CONFIGURATIONS
• CST’S PROPRIETARY MOMENT CARRYING CONNECTION DESIGN
• HIGH STRENGTH ALUMINUM ALLOYS USED FOR MEMBERS AND CONNECTIONS
• CURVATURE - POSITIVE, NEGATIVE, SINGLE OR DOUBLE
High quality prefabricated aluminum components and lightweight aluminum members ensure design success, speed of delivery and ease of construction.
CST is known throughout the world as the premier designer and manufacturer of geodesic domes, structural systems and assocative cladding for architectural and the many storage markets. Where quality, performance and ease of installation are important, architects and engineers around the world trust CST to provide a solution to make their ideas come to life.
Our palette of structural systems and the ability to design utilizing any type of cladding element in the marketplaces allows our products to be used in virtually any application. Exterior structures where corrosion plays a factor in the design drivers mandates a system constructed of non-corrosive aluminum components.
Some typical applications are:
-
Dome Roofs
-
Skylights
-
Canopies and Entryways
-
Roofs
-
Atriums
-
Vertical Glazed Applications
-
And many more...

At CST, we work with clients in order to facilitate many different shapes and forms. Certain projects require three dimensional framing in order to accommodate the spans or to match a certain architectural intent. Giving architects and engineers the tools to think 3D is what we do best. Using all aluminum components, state-of-the-art manufacturing equipment, design tools and a wealth of experience, we partner with our customers to make signature 3D structures possible.
Our proprietary Omni*Hub system is fabricated from all-aluminum components consisting of round tubular struts and solid spherical aluminum hub components. Structures are strengthened by a network of triangulated framing creating shape, geometries and forms only limited by the designer's imagination.
|
Architects worldwide have utilized the Omni*Hub system and a variety of cladding components to create dynamic structures for all architectural applications including flat clear span, vertical and overhead structures.
All products are manufactured under strict process controls using modern CNC machinery and state-of-the-art computer aided equipment.

CST all-aluminum truss systems are a very efficient and cost effective approach to covering space. Certain projects require reinforcement of the single layer lattice work. CST utilizes discreet trussing to reinforce framing and minimizes the visual impact of having structure in the three dimensional space allowing for pure light transmission and minimal framing.
Open or Enclosed Lattice
Trusses can be manufactured using a variety of extrusions, paint options and attachment methodologies to individualize the aesthetics and lend diversity to the final design. Alternatively, the trusses can be enclosed with distinctive cladding for acoustic |
or other design requirements. As with all of CST's aluminum structural components, the non corrosive framing ensures that there is no visual or hidden issues with rust or corrosion as may occur with painted steel members.
Custom Fabrication
CST's truss systems are custom designed to the customer's exact specifications and the project's structural requirements.

CST's attention to detail goes beyond proprietary structural members but carries over to creative and unique cladding systems and finishes.

 |
Cladding is more than just the materials, its a system. Designing cladding involves considering how the materials are supported, their spanning capacity, how they expand and contract relative to one another and how they will withstand the elements when they are first fabricated and well into the future.
While some companies consider cladding a second thought, CST makes it an integral part of the total solution from the early conceptual stages. In fact, geometry is generated based on the spanning and structural capacity of the selected cladding component itself.
|
With standard systems and custom engineering capabilities, no one can match CST's portfolio and ability to meet the demands of our customers for creative solutions that will surpass expectations.
CST's cladding support systems are:
-
Extremely Versatile
-
Integrated into the structural framework or attached directly to the outer chord of the structure
-
Fabricated from aluminum components, eliminating dissimilar material reaction
-
Utilize custom extrusions for optimization of the cost structure.
As a defining element of a building envelope, our cladding systems offer a degree of versatility rarely found in the architectural field. We often clad with but are not limited to glass, polycarbonate, fabric, metal panels, acrylic skylights, corrogated decking, and insulated roofing materials.
Design flexibility is among the SpectraForm system’s most compelling advantages. Indeed, each configuration creates its own unique elegant statement.
